Review of Using Electrolytes in Hot-Weather Runs

Sweating is how the body cools, but it also depletes electrolytes like sodium, potassium, and magnesium. In hot or humid conditions, electrolyte replacement becomes crucial.

Why Electrolytes Matter

• Sodium: Maintains fluid balance and prevents hyponatremia.
  
  
• Potassium & Magnesium: Support muscle function and prevent cramps.
  
  

Benefits of Supplementing

• Prevents cramping and dizziness.
  
  
• Supports sustained endurance.
  
  
• Reduces risk of dangerous imbalances.
  
  

Risks of Ignoring Electrolytes

• Hyponatremia from drinking only water.
  
  
• Muscle weakness or confusion in severe cases.
  
  

Practical Tips

• Use sports drinks, electrolyte tablets, or salt capsules in long, hot runs.
  
  
• Individualize — heavy sweaters need more.
  
  
• Practice in training to avoid surprises on race day.
  
  

Verdict

Electrolyte replacement is non-negotiable in hot-weather running. The key is finding the right product and dosage for your sweat rate and conditions.
